Network system and communication control method

摘要

A communication control method for a network system includes establishing a first communication path from a first virtual machine to be executed at a first information processing device to a second virtual machine to be executed at a second information processing device, using a plurality of switch devices, and establishing a second communication path from the first information processing device to a third information processing device using the plurality of switch devices, which differs from the first communication path, before moving the second virtual machine from the second information processing device to the third information processing device.

1. A communication control method for a network system, the communication control method comprising:
establishing a first communication path from a first virtual machine to be executed at a first information processing device to a second virtual machine to be executed at a second information processing device, using a plurality of switch devices, the first communication path being used for a first communication and a second communication, the first communication having a first priority corresponding to a type of a first application program that executes the first communication, the second communication having a second priority lower than the first priority, the second priority corresponding to a type of a second application program that executes the second communication; establishing a second communication path and a third communication path from the first information processing device to a third information processing device using the plurality of switch devices before migrating the second virtual machine from the second information processing device to the third information processing device, the second communication path being different from the first communication path, the third communication path being different from the first communication path and having a lower quality than a quality of the second communication path; and after migrating the second virtual machine from the second information processing device to the third information processing device, executing the first communication through the second communication path and executing the second communication through the third communication path.
